To r'Zl'whom it may concern Be it known that I, HENRY T. KNIGHT, a citizen of the United States, residing at Summerland, in the county of Jones and new and useful Improvements in Road-Machines, of which the following is a speciica tion, reference being had to the accompanying dra-wings;

This invention relates to new and useful improvements in machines for making and repairing roads. the object of the invention being to provide a new and-,improved machine suitable for grading, ditching and levcling,` in which the various adjustments of the scraper blades may be easily and quickly made, and in which the machine as a whole will be simple and economical in construction and operation.

Another o-bjectof the invention is to provide a machine of the above character whichv will' possess advantages in points of eiiiciency and durability, is inexpensive of manufacture and at thesame time is simple in lconstruction and operation.

W'ith the above and other objects in view, the invention consists in the novel features of construction' and the combination and arrangement o parts hereinafter more fully described, pointed out the claims and shown, in the accompanying drawings, in which-- i i Figure 1 is a longitudinal sectional view showing the device vapplied to the rear of the traction engine. Fig. 2 is a top plan, view, the scraper adjusting parts being removed.' Fig. 3 is-va rear elevation bowing the Scrapers arranged'in juxtaposrtion. Fig.

ner of securing the Scrapers to the rear of Figi 5 is a longitudinalV sectional view, andJ Fig.y 6 is a side elevation of one ofthe carriage members, "parts being broken away and in section.

Referring more particularly to the draw-4 ings, 1 indicates the platform of a traction ,which is arranged the wheels 2. At the rear of the platform in the rear lof the traction engine are the supporting frames 5 arrangedin longitudinal alinement and' provided upon the forward. edge thereofl with the' loops 6 which -between the bars S "cog and extending are adapted `to be arranged besidetlie' loops 4f upon the rear of the platform 1. Si rod 'Y is passed through the loops 4 and (3 to pivotally secure the supporting trames 5 to the traction engine.

Each of the `frames 5 comprise the longi tudinal bars 8 suitablyv connected at their ends to the transverse bars 9.1 Arranged in spaced relation and substantially n'iidway are the guide bars l0 having their ends secured to the transverse bars 9, Arranged between the bars 10 and VSand having their ends secured thereto are the strips 11 which form a suitable plat foim'uponv which the operator may stand, if desired. Extending 'upwardly from the transverse bars 9 and having their lower ends secured thereto are the brackets 11 which are arranged between the guide bars 10. Mounted within one oi' the upper corners of the brackets 1l is a threaded rod 12,

one end'of which is provided with a square portion 13 upon which a handle member may be engaged to rotate the-rod.

i' rranged between the guide bars lOand adjustably mounted upon the rod l2 is a Acarriage member 14 which is adapted to be adjusted from one end of the platform to the other upon the rotation t the rod 12, said' rod extending througl'i the threaded openings formed in the upper corners oit' the end pieces '15 of the carriage. Mounted within the carriage member 14 and disposed in a vertical position is a shaft 16, the lower end of which projects downwardly and is disposed beneath the bottom of the frame, said' shaft having its lower end bifurcated to form two spaced ears 17 which are disposed upon opposite sides of the central portion of a blade 18 and pivot-.ally secured to the upper edge thereof by means of a pin 19. Secured to the upper end of the shaft lare the spaced parallel arms 20 in the upper end of which. is mounted a shaft 2l. Mounted upon the shaft 2l and arranged between the upper ends of the arms is a sprocket 22. Engaging over the downwardly through the bottom of the carriage 14C is a chain 23, the

lower ends of which are secured to each end ofthe scraper blade 18.

Secured to the outer end of the shaft 21 is a handle member 24 whereby the shaft 21v may be rotated to adjust the scraper blade to various angles. Mounted upon the shaft 21 and arranged upon the outerside of one of the arms 2O is a' ratchet 25 which titi is adapted to be engaged by the pawl 26 pivotally mounted upon one of the arms to prevent the movement of the sprocket 22 when the scraper' blade has been adjusted to any desired position. Mounted upon the shaft 16 at a' point below the arms 2O is a hand lever 27 which is secured to the shaft by means oi the set screw 28, said set screw being removed to allow the lever 27 to be ad justed vertically upon the shaft. Mounted upon the shaft and arranged above the carnage bottom 14.- is a ratchet 29 which is adapted to be engaged by a pivoted pawl 30 to prevent rotary movement of the shaft when the scraper blade has been set to the desired position. Mounted upon `the shaft beneath the bottom of the carriage 14 is a guide member 31 which is provided at its ends with the openings 32 through which the chain 16 passes so as to guide the same upwardly through the openings in the'carringe member. Secured to the ends of the scraper blade 18 adjacent the chain 23 is a curved member 33, the intermediate portion of which is mounted in a suitable opening 34 formed in the shaft 16.

The supporting frames 5 are provided at 'the rear thereof with the loops 35 in which are attached the chains 36. Secured to the other ends of the chains are the cables 3T 'which are adapted to pass upwardly and down over the pulleys 38 supported atv the rear of the engine and ymounted upon the cross piece 39 which extends transversely across the top of the engine. The ends ot the cables then extend downwardly through a second set of pulleys a0. The cables may then he actuated by hand or they may ex- Lend forwarilly and wind upon a suitable drum which is operated by the engine to raise and lower the rear ends of the frames 5. From this, it will be seen that the scraper blades 18 may he raised entirely off the ground so that the machine may be moved from place to place.-

ln the 'use of' my improved road machine` vthe engine is driven along the road in the `center thereof while the carriages/14 may be adjusted lupon the rods 12 so that the dirt may be either scraped toward the center of tlie road or toward the outsides theref tion by means of the handle meinbei La:

of. .ln scraping the dirt :trom the center of the road to the outside thereof, the` car riages ifi are arranged at the inner ends of theframes 5 so that the scraper blades 18 will be disposed directly in the rear of the engine, butif it is desired to scrape the loose dirt toward the center of the road, the rar riages lll are adjusted toward the outer euds of the arms so as to scrape the dirt inwardly toward the center of the road. It will also be apparent that the scraper blades 18 may be adjusted longitudinally of the .frames and arranged in any desired angu which rotates the sprocket 22 to actuate the chain 23. i

From the above description taken in connection with the accompanying drawings, it will be readily apparent that I have provided a simple and durable road machine which is eutremely effective in its operation and which at the same time can be manu-- factored at a comparatively low cost.
